"...The second theorem of magic is that magic cannot spontaneously transfer from low-dimensional individuals to high-dimensional individuals - note that this is a 'one-way movement', which means that under normal circumstances, magic flows from high-dimensional to low-dimensional individuals. Dimension - Similarly, the passage of time from 'past' to 'future' also has a natural 'one-way movement' characteristic."

"... note the word - 'unidirectional' - it means that in the dimension of time, one side has 'direction' and the other side has 'no direction', it is 'asymmetric'; it also means, Even if you go from the past, to the present, back to the past, and then to the present again, the whole process is 'one-way', and there is no 'break' or 'parallel' in the timeline, let alone the parallel world you imagined. ”

“…The past is certain, and certainty is a convergent state, which is orderly, controllable, and observable; the future is uncertain, and uncertainty is a divergent state, which is disordered, chaotic, and Unobservable... This process of moving from order to disorder is one of the most essential concepts in the world.”

"...Some people may want to say, since the future is unobservable, what is the future calculated by divination? I need to emphasize one point here. The so-called unobservable future means that the future has infinite possibilities, and we cannot observe all possibilities. The future observed by divination is the greatest of all possibilities, but it is not an absolute outcome.”

At this point in the explanation, Baoyangzi stopped and gave the two young wizards some time to take notes. The three lines of large characters in mid-air have been densely outlined with many explanation terms.

The old man took another look at his 'blackboard', pinched his beard with satisfaction, then lowered his head and crossed his fingers.

The fragments of the tea cup on the ground slowly rose up piece by piece, spliced ​​and glued together along the way. When the old wizard held it, they had returned to their original shape and turned into an intact cup again.

Zheng Qing raised his head and happened to see this scene.

"This is not going back in time." Lao Yao reminded me from behind the desk: "It's just a small restoration spell transformation... Do you want another drink?"

He said the last sentence to Master Baoyangzi.

The old wizard twirled his gray beard, nodded invisibly, and continued to look at the two young wizards: "...from the perspective of dimensional theory, an orderly and controllable state is an adjective to describe low-dimensional phenomena; The state of disorder and chaos is an adjective describing high-dimensional phenomena... In other words, the past is a special low-dimensional state, and the future is a special high-dimensional state... The difference between high and low dimensions , is the magic foundation for us to return from the future to the past.”

He stopped again, picked up the cup and took a sip of clear tea.

"Isn't this self-contradictory?" Zheng Qing took advantage of this short gap and couldn't help but raise his quill, with confusion on his face: "If the past to the future is from low dimension to high dimension, doesn't that mean With..."

He was stuck, unable to think of a suitable adjective.

"It means that the magic power in the past must be greater than the magic power in the future in order to complete this reverse phenomenon from low dimension to high dimension." Jiang Yu obviously had a similar puzzlement: "But according to what you just analyzed... the past is low dimension again. Yes, shouldn’t the magic power of low dimensions be less than that of high dimensions? This sounds as strange as water flowing to higher places!”

"Yes, yes, that's what I mean." Zheng Qing nodded repeatedly.

"Very sharp."

A satisfied smile appeared on Baoyangzi's face: "The real magic theory is so counterintuitive. First of all, I can confirm that the magic of the past is more powerful than the magic of the future. This is why the most powerful wizard is called As the "old one"; secondly, magic power should flow from high dimensions to low dimensions, which is the basic concept of following the laws of magic; finally, convergent magic power may be more powerful than divergent magic power. The above three are collectively referred to as the magic power of time. 'Asymmetry' in dimensions. We know the past but not the future, which reflects the asymmetry of time. Similarly, high and low dimensions, convergence and divergence, order and disorder, controllable and. Chaos, observability and unobservability, etc., all describe this 'asymmetry.'

Zheng Qing opened his mouth slightly.

The old man's words, 'Converging magic may be more powerful than diverging magic', were like a spark, igniting an inspiration in his mind. Before he could decide whether to say that word, Jiang Yu next to him had already taken the lead. answered.

"Forbidden curse!"

There was a hint of surprise in the witch's urgent tone, and her crisp voice was like a handful of pearls falling on a jade plate: "The forbidden curse is a concept that has been converged to the extreme... The past timeline is also a state of convergence to the extreme! The instantaneous magic power of the forbidden spell far exceeds any kind of magic power known in the world, but the sum of all magic powers in the world is definitely more powerful than a certain forbidden spell!"

"It is indeed no longer a contradiction." Zheng Qing lowered his head and took notes frantically, adding to himself: "The so-called 'low-dimensional magic power in the past is higher than high-dimensional magic power in the future' is a relative concept... The magic of the ending timeline far exceeds the magic of the diverging future.”

"Very good, very good."

The old wizard rubbed the tea cup in his hand, pulled it into a brown pointer, waved it in the air, and clicked on the second concept just listed: "Now, let's introduce the next one. Concept, the relative flow rate of time!

We mentioned earlier that the ‘natural direction’ of time for everyone is from the past to the future.

But under this premise, everyone experiences the 'flow of time' differently - a very obvious example, for children, they feel that the speed of time is very slow, and each year is very long; but for adults, For humans, time passes very quickly, and each year is as short as a month in childhood.

There is a concept of 'time acceleration' in classical magic theory, which describes this phenomenon. Of course, some people call it ‘life acceleration’.

This concept talks about the fact that everyone's time experience will maintain a constant acceleration since birth. As they get older, time will pass faster and faster under the influence of this acceleration. Of course, in some cases, this concept will appear paradoxical, but this does not affect its validity in a broad sense.

The reason why it is mentioned is that it has a famous corollary that is still widely used today - powerful magic will make the time acceleration around the wizard larger. The more powerful the magic, the faster the time acceleration.

This also means that for a legendary wizard or a wizard of a higher level, his view of time is completely different from that of an ordinary wizard. The ancients said that "a great dream lasts for thousands of years", "a glance lasts for ten thousand years" and "the sky is like a day and the earth is a year" all describe this situation.

After wizards advance to the realm of great wizards, they need to 'store' their true bodies in their small world all year round. This is because they are too 'big' and 'heavy', and time will distort and accelerate around them, so in order to maintain 'relative harmony with the real world' ' state, they need to make a certain degree of compromise.

In a sense, this relationship between strong and weak is also a manifestation of ‘asymmetry’. "

Ps, am I writing a novel? (Self-doubt...) In the past, I thought it was too much to write a complete news report..._(:з　∠)_

Ps, after reading the conclusion of the next chapter, I really believed it (╯‵□′)╯︵┻━┻
